Association Between the Oral Health Status and Sociodemographic Factors Among 5-15-Year-Old Schoolchildren from Mallorca, Spain-A Cross-Sectional Study.

Oral health is a key indicator of general health, well-being, and quality of life. Sociodemographic factors can affect children's oral health status. The aim of this study was to analyze the sociodemographic factors that influence the oral health of schoolchildren in Mallorca. We conducted a cross-sectional observational epidemiological study in Mallorca, analyzing different indicators of oral health, such as the DMFT/dmft index and the Community Periodontal Index (CPI), and sociodemographic variables among 718 schoolchildren aged 5-6, 12 and 15 years. The DMFT (Decayed, Missing, and Filled Permanent Teeth) caries index was higher in public (Pub) schools than in private/charter (P/C) schools for children in the sixth grade of elementary school (Pub, 0.6918 ± 1.272; P/C, 0.323 ± 0.824; < 0.05) and in the fourth year of secondary school (Pub, 1.178 ± 1.724; P/C, 0.627 ± 1.195; < 0.05), as determined using a -test. First-grade elementary students with more highly educated mothers/guardians had a lower rate of DMFT (Decayed, Missing, and Filled Primary Teeth) caries than those whose mothers obtained only elementary-level education (higher, 0.800 ± 1.616; elementary, 3.333 ± 3.393; < 0.05). Regarding periodontal health, we observed that sixth-grade elementary schoolchildren with more highly educated mothers/guardians had more healthy sextants (higher, 3.987 ± 1.977; elementary, 1.333 ± 2.461; < 0.001). The sociodemographic and parental factors analyzed, such as the type of school and parents' education levels, significantly affected the oral health of the schoolchildren in this study.
